Agar is used as a solidifying agent in culture media instead of gelatin because it readily melts and it contains no nutrition for bacteria cultures.
<h3>What is agar?</h3>
Agar is a gelatinous material obtained from red algae and used in the preparation of culture medium.
Agar is used to solidify the culturemedium for bacteria growth, although, gelatin can also be used.
However, agar is preferred as a solidifying agent in culture media instead of gelatin because it readily melts and it contains no nutrition for bacteriacultures.
It reduces the chance of an extinction given a natural disaster. If there is more diversity and lets say a wildfire happens, more species would survive the event to repopulate the area
